Continuing the "long and short" theme of Page 1, we start with the
longest routes in California that are defined as 100% part of the freeway and
expressway system:

1.

US 101: 807
miles.US 101 runs from downtown Los Angeles, through
Ventura, Santa Barbara, San Luis Obispo, Monterey, San Jose, San Francisco,
Marin, and Redwood Country. It is all defined as freeway, although the reality
is that there are major portions that are not freeway, especially in the rural
areas.

5.

Route 89: 243
miles.Route 89 runs from I-5 to US 395 through Lassen.
Although designated as freeway, most of this is not constructed to freeway
standards.

California. 100% shimmering concrete.

to Nevada. It is the primary route from Southern California to Las Vegas. 100%

Shortest Freeways

Concluding the "long and short" theme of Page 1, we end with the
shortest freeways in California:

1.

Route 259: 1
mile.Route 259 is basically a ramp between I-215 and
Route 30 (future I-210) in San Bernadino.

3.

Route 221: 3
miles.Route 221 runs from Route 29 near Soscol Road to
Route 121 at Imola Avenue in Napa. This is a segment of Route 29 the state
tried to relinquish, but nobody wanted it.

Route 244: 1 mile.Route 244 is a short routing from I-80 to Auburn Blvd in Carmichael.
It is what is left of a planned eastern loop freeway in
Sacramento.

Route 234: 3 miles.Route 234 runs from I-5 near French Camp to Route 99. It is
unconstructed.

Route 242: 3
miles.Route 242 runs from I-680 to Route 4 north of
Concord. It is a former part of Route 24.

Route 217: 2 miles.Route 217 runs from the campus of the University of California at
Santa Barbara (UCSB) to Route 101 northwest of the City of Santa Barbara. The
state has authorized relinquishment of this, but it has not yet been
accepted.

Route 227: 2 miles.Route 227 runs from Route 1 south of Oceano to US 101. Only the
portion from Route 1 S of Oceano to US 101 near Arroyo Grande is in the Freeway
and Expressway system (and is the only constructed portion).

4.

Route 230: 4 miles.Route 230 runs from US 101 near the south city limits of San
Francisco to I-280 in San Francisco. It is unconstructed, and was originally
planned as longer eastern bypass route for US 101, running from San Francisco
to Route 87.

I-980: 2 milesThe "John B Williams" freeway, running from I-880 to I-580 in
Oakland. This was a major link during the Cypress

This was never upgraded to freeway. It is in Ventura county.
